I am an electronics engineer that works with image processing, numeric optimization, circuit design, embedded systems design, with knowledge in languages like C/C++, Python, MATLAB, Fortran, and some others, and have some experience with Cadence for circuit analysis and design (both digital and analogic), Xilinx for reconfigurable circuits design (FPGAs). My areas of research include biomedical applications, high performance computing, and many others.

In this project I equalized the histogram in each RGB channel, then converted the original image and equalized only the luminance channel using the HSI and YCbCr color schemes.

In this project I've used dithering, which is a technique for error propagation in quantization, to reduce the number of bits per pixel of an image and still maintain some of the original quality. I've used the masks of Floyd, Stucki, and Jarvis. This technique is used a lot in printers.

In this project I've used several Notch filters with different rejection frequencies to remove periodic noises in some images.

In this one I've done the histogram equalization of some images using fuzzy logic to transform each pixel. The membership functions defined if the pixel was dark, grey or white, and how much of it, and then its graylevel was modified based on that.

One of the projects I've done using image processing. This one is about connected component in a binary image, and also find the number of hole in the image.
